Pump Controls*
PUMP CONTROLS* Any, single or multiple, combination of
remote or load sense controls can be combined with the
built-in pressure compensator control if desired.
PRESSURE*
“P-1NN”
Pressure Compensator
Pump Controls*
Ensures maximum pump flow until unit reaches preset control
pressure setting and then regulates output flow to match the
requirements of the system while maintaining preset output
pressure. Pressure can be adjusted from 350 psi (24,1 bar)
working pressure up to the rated pressure of the pump.
“P-AXX”
Proportional Electronic
Pressure Compensator
Pressure compensator setting increases proportionally with an
electrical input signal. Pressure can be adjusted from 350 to
3750 psi (24,1 to 259 bar). A manually adjustable override
valve is used to set the maximum pressure settings.
Standard Load Sense
w/ Pressure Compensator
“P-1NN/F”
A constant output flow is maintained for a given (customer
supplied) flow control valve setting regardless of changes in
drive speed and/or working pressure. The load sense
differential is 180 psi (12,4 bar) and is not adjustable.
“P-BXX”
Inverse Proportional
Electronic Pressure Compensator
Pressure compensator setting decreases proportionally with
an electrical input signal. Pressure can be adjusted from 350
to 3750 psi (24,1 to 259 bar). A manually adjustable override
valve is used to set the maximum pressure setting. Generally
used for fan drive circuits.

Adjustable Load Sense w/Pressure “P-1NN/J”
Compensator Override
Adjustable load sense w/pressure compensator “P-1NN/J.”
A constant output flow is maintained for a given (customer
supplied) flow control valve setting regardless of changes in
drive speed and/or working pressure. The load sense differential
is adjustable from 180 to 700 psi (12,4 to 48,3 bar).
Remote Controls for Pressure
Compensator Functions
A customer supplied remote control valve can be easily
added to any of the “PVM” Pumps allowing pressure adjustment
control to be convenient to the operator while the pump may be
located convenient to the operated device.
Same as “P-1NN/J” except with an internal orifice to vent load
sense pressure to drain when the load sense is not active or
during shutdown. The load sense differential is adjustable from
180 to 700 psi (12,4 to 48,3 bar).
Note: RP (Remote Pressure) lines of multiple pumps can
not be tied together for unloading or controlling with a
common remote pressure control valve. A dedicated valve
is required for each pump.

MULTIPLE PUMP COMBINATIONS
Two or more Oilgear “PVM” axial piston variable delivery pumps can be integrally coupled
together and driven from a single shaft. In most cases (see Specifications) both pumps can be
used at full rated output. Pump deliveries can be combined for large volume circuits or
deliveries can be used individually. See the following table and calculations for Allowable
Thru-shaft Torque.
How to calculate torque for each pump
Multiple Pump Combinations
T (in. lbs.) = Pressure (psi) x Displacement (cu. in./rev.) *
5.625
22
Add the respective torques for each unit:
T1 = front pump torque required
T2 = second pump torque required
Tn = Additional pump or torque for any other driven device
T1 + T2 + Tn Sum must be less than T max. shown in table
